Abstract
The invention discloses a method for purifying high salinity wastewater by electrostatic adsorption. The method comprises the steps of: providing a water treatment device comprising a container and a plurality of electrodes arranged in the container, wherein the plurality of electrodes are alternately arranged on a first side and a second side in the container, the first side and the second side are arranged in opposite, the electrodes on the first side and the electrodes on the second side are respectively connected to the positive pole and negative pole of a power supply, a third side and a fourth side of the container are respectively provided with a water inlet and a water outlet, the plurality of electrodes define a snakelike water flow channel, and each electrode from outside to inside comprises a glass fiber layer, an activated carbon fiber layer and a conductive metal layer; and introducing the high salinity wastewater into the water treatment device from the water inlet of the container, passing through the snakelike water flow channel, and discharging from the water outlet. The method uses the electrostatic field provided by low voltage produced by a solar panel for the treatment of high salinity wastewater. The novel electrode material improves the treatment efficiency, reduces the energy consumption, improves processing efficiency, saves energy and reduces the cost.
Description
technical field [0001] The invention relates to a method for purifying high-salt wastewater by electrostatic adsorption. Background technique [0002] High-salt wastewater refers to wastewater with a salt content of at least 1%, mainly from chemical plants and oil and natural gas collection and processing. Nowadays, physical and chemical methods are mainly used to treat salt ions in high-salt wastewater, such as distillation, electrodialysis, ion exchange, reverse osmosis, etc., but these water treatment and desalination technologies have varying degrees of deficiencies, such as distillation The required energy consumption is relatively high, and the ion exchange method is not economical, the resin is easy to reach saturation, and the regeneration cost is relatively high. However, there is an urgent need for purification devices with low cost and high adsorption efficiency. Contents of the invention [0003] An object of the present invention is to solve at least the abo...
